Answer 1: Discrete probability distribution is the one in which assigns a distinct probability to each value of the occurrence. In such a scenario, each occurrence of the subject values can be assigned a non zero probability. For example, the values of occurrence of 3 and 4 heads will have different values of probability under the discrete probability distribution.

A discrete probability distribution differs from a continuous probability distribution, by only taking values on a discrete set (like the whole numbers) instead of a continuous set. The geometric distribution is a discrete probability distribution which measures the number of times an experiment must be repeated before a success occurs. For example, in this problem, we will roll a fair six-sided die until the number six occurs, at which point we stop rolling. (a) If we are rolling a die,...
